PURPOSE:To constitute it cheaply using standard parts by dividing a reflector, which constitutes a luminaire, into a center reflector and two pieces of side reflectors, and coupling the rear side of divided each reflector integrally with a plurality of band-shaped reinforcing plates. CONSTITUTION:A reflector is divided into a center reflector 11 and two pieces of side reflectors 11b. Such narrow rise pieces as to parallel the bent side face of the reflector are provided in parallel on both side edges of this center reflector 11a. Bent pieces 11c are made at two pieces of side reflectors 11b by bending the upper parts, respectively, and the bent pieces 11c are arranged on both sides of the center reflector 11a, being opposed to each other, and the rears of these reflectors 11a and 11b are coupled by a plurality of band-shaped reinforcing plates 12. According to this constitution, there in no necessity to change it at all other than change the reflector, and it can cope enough with a large capacity of air conditioning facility, using standard parts which constitute the system ceiling luminaire. |
